What do a Rogowski coil, a magnetic core, and a hall effect sensor have in common? They are all ways you can make oscilloscope probes that measure current. If you think of a scope as a voltage ...

Measuring AC current (220-V mains RMS current) is not as simple as measuring DC current. In DC current measurement, you can simply hook the oscilloscope probe to the shunt resistor and calculate the ...

If you want to measure voltage you reach for a voltmeter. Current? An ammeter. Resistance? An ohmmeter. But what about measuring AC power? A watt meter? Usually. But if you know what to do, you could ...

Saelig Company, Inc. has announced availability of the CLIPPER CLP1500V15A1 - an scilloscope adapter that allows small voltages to be measured in the presence of very high voltages, such as those ...

My colleagues and I are not conscious of any act of impropriety in this matter, but the comments above give a misrepresentation of the position, to which I must reply briefly. It was shown more than ...
